Na wear resistance,Ɛwɔ hɔ 3 nneɛma atitiriw,basalt liner,cast dade ne alumina ceramic.
1st,Basalt a wɔde yɛ adwuma
Mfaso:bo a ne bo nyɛ den
Wear resistance aspect:friableness ,splintery.Thickness bɛyɛ 25-35mm,po 40mm.When mu wɔ mpaapaemu,basalt fã no bɛsɛe a ɛka ho ne fango a wɔayam no kɔ crack.What's more,mfinimfini fã no betumi anya pore,wear resistance no nyɛ anohyeto.
2nd,dade a wɔatow
Cast dade yɛ kɛse de di dwuma wɔ wear resistance,ayɛ mfiridwuma no yɛ simple.Hardness about60HRV.Thick thickness,dodow heavy.High carbon content,poor weldability.
3rd, Nkuku a wɔde hyɛ mu.
Nneɛma yɛ Over 92% alumina,hardness so HRV85.Surface nyinaa mu ne akyi yɛ smooth.Wear resistance yɛ bɛboro mpɛn 10 yiye sen cast steel.Weight yɛ bɛyɛ 1/3 kakraa bi sɛ wɔde toto koro no ara thick dade paipe,easy adwumayɛ.
